CECIL c. YZNAGA, on SEBASTIAN, Texa AIR-COMPRESSOR.

Specification of Letters Patent.

Patented May so, 1919.

Application filed June 8, 1918. Serial No. 238,951.

To all whom it may concern Be it known that 1, Client C. YZNAGA, acitizen of the United States, residing at Sebastian, in the county ofCameron and State of Texas, have invented certain new and usefulImprovements in Air-Compressors, of which the following is aspecification.

This invention relates to air pumps, and more especially to those havinga solid pis ton; and the object of the same to pro duce an aircompressorfor use on an automobile.

The invention consists primarily in a tank lnovably attached to the axlecasing, a pump alongside the same, 'and gearing connections between thedrive shaft of the pump and the hub of a wheel whereby when the partsare thrown into operative position air may be stored in the tank forfurther use.

The invention also consists in minor details of construction, all ofwhich will be set forth in the following specification and claims andare shown in the drawings wherein Figure his a plan view of one end ofthe rear axleot an automobile with this invention applied, showing thesame in active position in full. lines and out of ac ive position indotted lines,

Fig. 2 is an enlarged sectional detail of the inner end of the tank,

Fig. 3 is an enlarged sectional detail of the toothed band forapplication to thewheel hub.

As for the auton'iol'iilc, we are interested only in the casing C of theaxle at one side of the differential l), and with one driving wheel. W,concerning which parts no invention has been made.

Corning now to the details of the present invention, the numeral 1designates a tank having near its inner end a yoke 2 provided with twoeyes 3 and at its outer end a single eye l. 5 and 6 are clips made intwo parts as shown in Fig. 2, and adapted to be suported on the axleeasing C by means of liolts 7, these clips having yokcs 12 whereof eachhas two eyes 13 adapted to aline with the eyes 3 for the reteptionthrough the eyes of a pin 11 as best shown in Fig. 2. Another clip8 is secured upon the casing C near the difierential D, and this cliphas an eye 14 adapted to register with the single eye 4 at the outer endof the tank 1 when the latter is swung to the position indicated. indotted lines in Fig. 1, and at this time another .pin inserted throughthese eyes holds the tank in this position. It is clear that by removingthe pin 11 from the outermost clip 6 and swinging the tank, the. samepin can be utilized to lock the tank in its inactive position parallelwith a nipple 1(3 and valve 15 so that a hosemay be slipped over theformer and the flow of air controlled by the latter, and obviouslythehose can be led to a tire which is to be filled or to any other pointwhere compressed air is desired. v The pump comprises a cylinder 20, apiston 21 reciprocating therein, a piston rod 22, and a shaft 23 havinga crank 2+1: with which said rod is engaged; and ou the outer end of theshaft is a pinion 25 adapted to mesh with a ring of gear teeth 26carried by a band 27 which is provided with set screws 28 as best seenin Fig. This band is adapted to be slipped over and fastened upon thehub of the wheel W when the latter is oil the axle, and then it can bereplaccd. Obviously, turning of the-Wheel causes turning of the toothedband, and the meshing ofthc teeth 26 with the pinion 25 causes rotationof the shaft 23 and of the crank 24 so that the piston 21 isreciprocated within the cylinder and airnpumped.

into the tank in a n'ianner which will be clear. This may occur whilethe'inachine is.

running, but I prefer at this timeto swing the device to the inactiveposition indicated in dotted lines when the pinion comes out of meshwith the gear teeth and the pump does not operate. When air isneeded,the pin 11 is withdrawn and the device swung to active posit-ion whenthe pinion is in mesh with the gear teeth, and then when this end of theaxle is jacked up and the wheel rotated by driving the motor, air willquickly be stored under pressure in the tank and can. be withdrawnthrough the nipple and hose for use where desired, or,it is quitepossible to permit the parts to remain in active position so that "asthe car is progressin air will be stored in the tank to be used litterwhen desired. in that case the tank ought to be provided with asafety-valve (not shown), and in any case it is preferably provided witha gage as indicated at 30. The parts are of any desired sizes,proportions, and

shapes, and changes may be made without departing from the principle ofmy invention.

The foregoing description and the drawings have reference to what may beconsidered the preferred. or approved. form of my invention. It is tobeumlerstood' that I may make such changes in construction andarrangement and combination of parts. ma terials. dimensions. et cetera,as may prove expedient and fall within the scope of the appended claims.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent. is

1. In an air compressor. the combination with a tank having a valvedoutlet. a pump whose, cylinder is mounted tank. ,antl means forreciprocating the pump-pistonz ot' a pair of supports for one end of thetank to which it is pivotally attached. the pivot pin being removable.and a third stlpport. tor the remote end of the tank adapted to receivethe same pin when removed from one of said first-named sup ports.

2. In an air comprestor, the combination with a tank having a yitlvedoutlet. a pump whose cylinder is mounted alongside the tank. and meansfor reciprocating the pump-piston; of an axle casing. three. clipsmountedthereon and having eyes. two eyes carried by one end of the tank.pins removably engaging said eyes aml those on two of said clips. and asingle eye carried by the renmtejtmd ot the tank and adapted to alinet'lth the eye in the remainipg clip for receiving a pin. for the purposeset forth.

3. In an air compressor for automobiles. tllGCOlllblHiltlOll with theaxle easing. a driving wheel, and a band of gear teeth adapted forattachment to the hub of the latter; of a tank hingedly mounted on saidcasing. a pump whose cylinder is carried by the tank and swings with it,a piston within said cylinder. a crank shaft for driving said piston.and, a. pinion on the shaft adapted to mesh with said gear teetlrwluuithe tank and pump are swung to one position and to move out of mesh whenthe parts are swung to the opposite position, for the purpose set.forth. i

4-. In an air conmressor for automobiles, the combination with the axlecasing a driv ing wheel, and'a band of gear teeth adapted alongside the.to attachment to the hub of the. latter; of a plurality of eyes carriedby said casing, a tank, two eyes in one end of the tank and. one in theother, removable pins connecting said two eyes with two of those on thecasing to hold the tank in position with said pinion in mesh with saidgear teeth and the remaining eye of the tank adapted to register withthe remaining eyeionthe casing. to hold said pinion out. of mesh, forthe purpose set forth.

5. In an air compressor the combination with the axle. *asing and thedrlving wheel; ot a toothed band for detachable connection with saidwheel. a tank. a pump. the cylinder thereof carried by the tank.ump-drivingmechanism including a pinion adapted to mesh with saidtoothed band. and a hinge support between the tank and axle casingwhereby in one po sition of the tank and pump its pinion meshes withsaid band and in another position thepinion is out of mesh with theband, tor the purpose set forth.

ti. In an air compressor for automobiles, the combination with a band ofgear teeth carried by one wheel. and a plurality of sup ports mounted onthe axle casing adjacent. said wheel: of a tank pivotally mounted on oneof said supports. means For fastening it selectively to either of theother supports t'or holding it in one of two positions, a pump carriedby the tank and communicating with its interior and pump-drivingmechanism including a pinion for engagement with said gear ring in oneposition of the tank only. as described.
